(a) What is meant by unidentate, didentate and ambidentate ligands? Give two examples for each.
(b) Calculate the overall complex dissociation equilibrium constant for the `Cu(NH_3)_(4^(2+))` ion, given that `beta4` for this complex is `2.1xx10^13`.

Text Solution

Verified by Experts

The overall dissociation constant is the reciprocal of overall stability constant i.e., `(1)/(beta_(4))=4.7xx10^(-14)`
